The picture above is of a sidewalk over which I run most days. If you look closely, you’ll see that a section of the sidewalk has been replaced with fresh, new cement. The reason is that the old section was pushed up, broken, and a terrible trip hazard on dark winter mornings.
Naturally I’m pleased with the improvement, but the lean thinker in me can’t help but see a flaw in this fix. After all, look just to the left of the sidewalk and you can see the tree that caused the sidewalk damage in the first place. In this case the root cause of the problem is, well, a root. Assuming the tree continues to grow and the roots continue to spread, it seems like we’ll be paying to replace this sidewalk again in the future.
Anyone else out there patching a sidewalk with a tree growing underneath it?
